AT27C040-90PU

The AT27C040-90PU is a 4194304-bit low-power high-performance one-time programmable Read-Only Memory (OTP EPROM) organized as 512k by 8-bit. The AT27C040 requires only one 5V power supply in normal Read mode operation. Any byte can be accessed in less than 70ns, eliminating the need for speed reducing wait states on high-performance microprocessor systems. The scaled CMOS technology provides low active power consumption and fast programming. Power consumption is typically 8mA in active mode and less than 10μA in standby mode. The AT27C040 is available in a choice of industry standard, JEDEC-approved. The device features two-line control (CE, OE) to eliminate bus contention in high-speed systems. The AT27C040 has additional features to ensure high quality and efficient production use. The rapid programming algorithm reduces the time required to program the part and guarantees reliable programming. Programming time is typically only 100μs/byte.
